BACKGROUND OF THE INVENTION Field of the invention Binders for the shuttle boxes of looms of the flying shuttle type.

Description of the prior art It is common knowledge to those skilled in the art that binders now in use in modern high speed looms produce various loom troubles, among which are: rebounding shuttles; damaged or broken shuttle boxes and/or shuttles; the production of cloth having loose picks; and frequent loom adjustments and poor bobbin transfers.

Summary of the invention A primary object of the invention is to provide a binder which is capable of withstanding the repeated and considerable impacts of the shuttle thereagainst without un due distortion, unwanted breakage and/ or wear.

A further object is to provide a binder which may be readily installed in the shuttle boxes of existing looms without modification of the shuttle box.

Still another object of the invention is to provide a binder which will automatically overcome the enumerated disadvantages of the prior art binders while permitting higher machine speeds and more accurate loom operation.

A salient feature of the invention is the provision of a binder having a novel wear surface capable of absorbing the initial impacts of the shuttle, thereby greatly prolonging the life of the binder.

Brief description of the drawing FIG. 1 is a broken, side elevational view of a binder embodying a preferred form of the invention; and

FIG. 2 is a bottom plan view thereof.

Description of the preferred embodiment Before proceeding with a detailed description of the figures of the drawing, let it be understood that the binder embodying the invention is spring biased and pivotally mounted in the usual shuttle box so as to be disposed in the path of travel of the shuttle, whereby, upon contact of the shuttle with the binder, the speed of the shuttle is slowed and the binder is deflected against the usual protector finger. Such a basic structure is described and shown in United States Patent No. 2,111,962 to Brown and is so well known in the art that same has not been reproduced in the accompanying drawing.

With reference to the drawing, a shuttle binder generally indicated by 10, preferably, although not necessarily, made of wood, is shown as comprising a main body portion 12, a toe portion 14 at one end of said body portion and a heel portion 16 at the opposite end of said body portion.

As is conventional, the lower surface of main body portion 12 is substantially plane throughout and is provided, over a portion of its length, with a covering layer 18 of leather or similar frictional-type material which acts in the manner of a brake to slow the speed of the flying shuttle, the covering material being fixed to the lower surface of the main body portion by any suitable means, as by an adhesive or the like, not shown.

A swell or shuttle engaging face 20 of the main body portion and an inwardly-facing face 22 of the toe portion are provided with a layer of high impact material 24, in the nature of epoxy or the like, bonded to the main body portion and toe portion in any suitable manner.

Superposed upon the layer of epoxy is a wear plate 26 preferably formed from a non-resilient metal in the nature of stainless steel or the like and fixed to the main body portion and to the toe portion as by bolts or screws 28 or weldments or equivalent.

The point of jointure between wear plate 26 and covering layer 18 is reinforced by a thin strip 30 of epoxy or like material, said point of jointure additionally being angularly disposed relative to the longitudinal central axis of the binder, (represented by imaginary line X-X in FIG. 2), thereby to better 'withstand the wear and tear of the shuttle passing thereunder.

A similar reinforcing strip 32 also of epoxy or like material, is provided in an angularlydisposed groove 34 in the lower surface of covering layer 118.

The swell and the nose portion of the binder take the main brunt of the shock of impact when the binder is struck by the shuttle, indicated by S and shown in phantom in FIG. 1.

The combination of the metal wear plate and epoxy provided on the swell and nose portion serve to cushion the binder from this shock, thereby greatly prolonging its life.

Similarly, the angularly-disposed epoxy reinforcing strips, being disposed at points of potential weakness also strengthen the covering material.

Since these reinforcing strips are angularly disposed, they do not demonstrate the tendency to grab the shuttle as it travels thereunder, as would happen if they were normal to the binder axis, thereby assuring smoother loom operation.

The opposite face of the toe portion is provided with the usual hard rubber or fiber protective pad 40 engageable with the aforementioned protector finger, not shown, and the opposite face of the main body portion is provided with the usual hard rubber or fiber protective pad 42 engageable with the aforementioned biasing spring, also not shown, as the binder is deflected by the shuttle.

The binder is pivoted on a suitable pivot pin, not shown, which operates in a bushing 50 of rubber or other similar resilient material extending transversely through heel portion 16, the rubber bushing permitting the desired lateral displacement of the binder upon impact from the shuttle S.

Bushing 50 is provided with an inner lining of nonresilient material 52 in the nature of nylon or the like to minimize wear at the pivot.

The resilient pivot mounting automatically permits the binder to compensate for shocks at the heel portion, body portion and toe portion.

I claim:

1. A binder for a shuttle box of a loom of the flying shuttle type wherein the binder is pivotally connected to the shuttle box comprising:

(a) a main body portion having a swell and a nose portion;

(b) a frictional covering layer of leather fixed to said main body portion and terminating at said swell;

(c) a combination wear resistant and cushioning means disposed exteriorly of and fixed to said swell and to said nose portion for absorbing the impact of the flying shuttle on the binder;

((1) said combination wear resistant and cushioning means comprising an epoxy layer and a superposed metal wear plate;

(e) reinforcing strips spaced along the outer surface of said covering layer;

4 (f) said reinforcing strips being epoxy and being disposed at an angle to the longitudinal axis of the binder, and

(g) resilient means at the pivotal connection between the binder and the shuttle box.

2. A binder according to claim 1, wherein said resilient means at the pivotal connection between the binder and the shuttle box comprises, a resilient bushing sleeving a wear-resistant bushing mounted on the pivot.
